Bird behavior is the study of the actions, interactions, and communication of various bird species. This research area examines how birds behave in their natural habitats, how they communicate with each other through calls and body language, and how they adapt to environmental changes. Researchers in this field may study mating behaviors, nest building, feeding habits, social structures within bird populations, and migration patterns. By understanding bird behavior, scientists can gain insights into the ecological and evolutionary factors that shape bird populations and communities.
